You’d better lower the degree when matching the lens, really, right?

Abstract: the role of mydriasis is to fully relax the regulation of ocular ciliary muscle. Optometrists can more accurately detect the refractive state of patients through medical optometry. Ghosting is mostly due to astigmatism. It is recommended to go to an eye hospital for examination and treatment.

summer vacation has passed, and many people still come to the eye hospital for medical optometry and glasses every day. Let’s say what should be paid attention to when matching myopia glasses and what common misunderstandings should be avoided? Take a look before matching the lens. It’s useful!

who needs glasses?

1. It is determined to be true myopia by medical optometry.

2. Hyperopia refractive state inconsistent with the patient’s age.

3. Astigmatic refractive state inconsistent with the patient’s age.

the above three cases must be equipped with glasses! And pseudomyopia does not need glasses!

who needs mydriasis before glasses?

and

mydriasis are generally more common. For children and adolescents who do optometry for the first time, adults will recommend mydriasis only when visual fatigue or visual correction is not normal. The role of

and

mydriasis is to fully relax the regulation of eye ciliary muscle. Optometrists can more accurately detect the refractive state of patients through medical optometry. Ghosting is mostly due to astigmatism. It is recommended to go to an eye hospital for examination and treatment. Can

and

astigmatism be cured? The astigmatism of

and

is caused by the different diopters in two mutually perpendicular directions of the eye. Astigmatism cannot be cured, and can only be further deepened by wearing glasses to correct and control astigmatism.

in the final analysis, in addition to a small part of genetic causes, most of myopia is caused by poor eye habits. The function of myopia glasses is to make you look comfortable and clear. So, what minefields do you need to pay attention to?

and

you’d better lower the degree when matching glasses? The purpose of

and

glasses is to assist vision, so that the eyes do not have to squint hard to see. If the degree is insufficient, the ciliary muscle responsible for adjusting the focal length will be over adjusted and continue to spasm. It is easy to get tired for a long time, but it may worsen your vision faster.

arbitrarily reduce the degree of glasses, the degree of myopia will not decrease, but will increase faster. Such glasses do not play a role at all. Instead, they wear deeper and deeper!

and

need to be worn every day after matching glasses?

1. For children with low myopia and normal adjustment function, they can not wear glasses when looking close. When they can’t see clearly, they must wear glasses to avoid their bad eye habits such as squinting and crooked head, otherwise they will aggravate the development of myopia and glasses don’t play a role;

2. For children with low myopia but abnormal adjustment function, it is recommended to wear glasses whether looking far or near, which will better control the development of children’s myopia. If children continue to use their eyes when their eyes are tired, wearing glasses will alleviate their eye fatigue and achieve the effect of preventing the deepening of myopia;

3. Medium and high myopia must wear glasses all day.

and

medical optometry glasses play a very important role in the visual effect and wearing comfort of myopia patients. Therefore, when matching glasses, we must choose a professional ophthalmic hospital.
